Product

The products covered by this manual are

the BPF fused substation by-pass switches

for medium voltage electrical distribution

switching.

These products are designed for distribution

switching only at their rated capacities. They

cannot be field modified for capacities other

than what was shipped with the units. If a

different capacity is desired, contact your

supervisor or factory representative to se-

cure the appropriate unit.

Overview

Function

These products are non-loadbreak discon-

nect switch and fuse combinations designed

to provide a means for by-passing, discon-

necting and isolating reclosers on the elec-

trical distribution system.

General

The BPF By-Pass Switch is a single-phase

fused hook stick operated switch. It is nor-

mally used with a companion switch such

as a Chance M3S, station class hook stick

switch. The BPF By-Pass switch is used for

manually disconnecting a recloser without

interrupting normal electrical service while

continuing to provide over-current protec-

tion. Standard variations are:

A. Left or right fuse mounting.

B. Te rminal connectors.

The BPF disconnect switch has no inherent

current making or breaking rating. The fuse

is capable of interrupting over-currents

within its assigned rating. Both switch and

fuse include load break hooks for use with a

load break tool. The BPF has no dead-end-

ing provisions.

Specifications

Select the proper BPF switch for each in-

stallation with consideration to system and

short circuit recovery voltage, continuous

current, available short circuit over-current,

short time current withstand, lightning im-

pulse withstand and variations. If there is

concern about the use of this switch as

rated, consult your supervisor before instal-

lation.

• Nominal voltage ratings of 14.4kV or

25kV (model dependent)

• Lightning impulse peak withstand ratings

of 110kV or 150kV (model dependent)

• Switch continuous current rating of 600

amperes

• Switch short time current withstand

rating:

– 25kA symmetrical, 1 second

– 65kA peak

• Fuse continuous current ratings of 100 or

200 amperes (model dependent)

• Fuse interrupt ratings of:

14.4kV nominal voltage rating

– 7.1kA symmetrical, 10kA asymmetrical

for 100 ampere fuse holder

– 8kA symmetrical, 12kA asymmetrical

for 200 ampere fuse holder

25kV nominal voltage rating

– 5.3kA symmetrical, 8kA asymmetrical

for 100 ampere fuse holder

– 6.6kA symmetrical, 10kA asymmetrical

for 200 ampere fuse holder

• Rating of the fuse holder is given on the

switch name plate. Consult factory repre-

sentative prior to using any other fuse

holder.

Switch Variations

A. Left or Right Fuse Mounting

Left or right fuse mounting may be speci-

fied. A left mounted fuse is to the left of the

operator when viewed from the front of the

switch. A right mounted fuse is to the right

of the operator when viewed from the front

of the switch. This selection allows the BPF

to be tailored to fit the requirements of the

application. Illustrations in this manual show

only a left fuse mounting. Right fuse mount-

ing will be opposite as shown but does not

change the installation or operation

procedures. (continued next page)

CAUTION

Installation

• Install an appropriately rated fuse link in

the fuse holder.

•To install the fuse link in the fuse holder,

remove the cap from the upper ferrule of

the fuse holder assembly.

•To connect the fuse link and arc shortening rod, remove the screw-type button-head and

washer (if equipped) from the fuse link.

• Screw the arc-shortening rod (attached to cap) onto the fuse link and tighten firmly (See

Figure 2).

• Slide the fuse link cable into the top of the fuse holder and pull out at the lower end.

• Replace the cap or arc shortening rod assembly on the upper fuse holder ferrule and

tighten with a wrench.

• Holding the fuse holder at the lower end, rotate the link ejector about its pivot until it stops,

making certain that the tab on the link ejector engages the latch on the lower fuse holder

ferrule (See Figure 3).

• Hold the ejector in this position and feed the cable over the link ejector channel and in a

clockwise direction around the un-threaded portion at the base of the stud (See Figure 4).

•Maintain tension on the fuse link cable and tighten the fuse link attachment nut with a

wrench.

• Cut off excess fuse link cable.

High Voltage Electrical Arc Hazard

May cause moderate injury or property damage.

Do not remove or damage the small tube on the fuse link. It is an integral part of the fuse link and removal or dam-

age may result in the fuse’s failure to interrupt an over-current.

Install Fuse Link

High Voltage Electrical Arc Hazard

May cause moderate injury or property damage.

Do not use 100 ampere or smaller fuse links in 200 ampere fuse holders by employing washers or other means.

This action may result in the fuse’s failure to interrupt an over-current.

High Voltage Electrical Arc Hazard

May cause moderate injury or property damage.

Do not replace an arc-shortening rod with a standard cap. The rod is

required to achieve the designed interrupting rating and use of the

fuse holder without the rod will reduce the fuse’s interrupting capabil-

ity and may cause the fuse to fail to interrupt an over-current.

NOTE: Fuse holders using an arc-shorten-

ing rod require the use of removable button-

head fuse links.
